Socket Fusion Defined
Injection molded fittings are typically used when implementing the socket fusion process. This procedure consists of a heating phase, a welding phase and a cooling phase. This process is usually conducted manually using a socket fusion tool. The tool includes fixtures to match the appropriate locations of both components and heats them as part of a single joining operation. A metal socket heater heats the outer circumference of the pipe. The heating process occurs along a defined length which will vary depending on the diameter and size of the pipe and fitting being welded.
The spigot fitting on the opposite side of the hot plate heats the inside of the injection molded fitting. The length of the heated region is approximately the same as it was for the pipe. The fitting AND the pipe are each exposed to heat for a specified heating times. Once the appropriate time is reached, the heated spigot tooling is removed and the pipe and fitting are brought together using force. A weld is then formed and, once the joint is cooled, the process is complete. The most certain way to get a high quality socket joint is to have a trained specialist use proper tools according to industry joining standards. There are also electrofusion sockets available for welding.
